SURFACE IRRIGATION SYSTEM PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended,
and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Brunswick County
Brunswick County
FOR THE
continued operation of a 24,000 gallon per day (GPD) spray irrigation treatment and disposal facility consisting of
a 720,000-gallon treatment lagoon, a 1,080,000-gallon storage lagoon, a tablet chlorinator, a pump station
equipped with a flow meter, an approximately 5.75-acre spray irrigation disposal field and all necessary piping
and appurtenances to serve the Brunswick County Government Complex, with no discharge of wastes to the
surface waters, pursuant to the application received April 2, 2004, and subsequent additional information received
by the Division, and in conformity with the project plan, specifications, and other supporting data subsequently
filed and approved by the Department of Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until May 31, 2009, shall void Permit No.
WQ0003597 issued August 30, 1999, and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. The Division recognizes that the disposal site has a capacity to assimilate wastewater at a rate less
than the permitted flow rate of 24,000 GPD. Therefore, as a part of this permit, necessary actions
such as pumping and hauling or diverting flow through other approved means shall be taken such that
flow in excess of the permitted rate of 24,000 GPD not be applied to the disposal site. This permit
provides permission to transport through pump and haul operations, 24,000 GPD of wastewater from
the wastewater lagoon system to the Northeast Brunswick Wastewater Treatment System with no
discharge to surface waters. The approval for the permission to transport the 24,000 GPD shall
become voidable unless the agreements between the County of Brunswick and S & B Maintenance,
Inc. for hauling the wastewater are in full force and effect.
2. The surface irrigation facilities shall be effectively maintained and operated at all times so that there
is no discharge to the surface waters, nor any contamination of ground waters, which will render them
unsatisfactory for normal use. In the event that the facilities fail to perform satisfactorily, including
the creation of nuisance conditions or failure of the irrigation area to adequately assimilate the
wastewater, the Permittee shall take immediate corrective actions including those actions that may be
required by the Division of Water Quality (Division), such as the construction of additional or
replacement wastewater treatment and disposal facilities.

3. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface
or groundwaters resulting from the operation of this facility.
4. The residuals generated from these treatment facilities must be disposed in accordance with General
Statute 143-215.1 and in a manner approved by the Division.
5. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
6. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under separate
ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainage ways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between treatment/storage units and any wells, and
g) 50 feet between treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for this waste
treatment and disposal system. These buffers are not intended to prohibit or prevent modifications,
which are required by the Division, to improve performance of the existing treatment facility. These
buffers do, however, apply to modifications of the treatment and disposal facilities that are for the
purpose of increasing the flow that is tributary to the facility. These buffers do apply to any
expansion or modification of the irrigation areas and apply in instances in which the sale of property
would cause any of the buffers now complied with, for the treatment and disposal facilities, to be
violated. The applicant is advised that any modifications to the existing facilities will require a permit
modification.
7. The disposal system shall be connected to a rain or moisture sensor that shall indicate when
wastewater application is not appropriate in accordance with Condition II(4) of this permit.
8. A usable green area shall be maintained for wastewater disposal. The green area shall have the
capability of accommodating the average daily flow of the facility being served without exceeding the
loading rates of the green area. A "green area", as defined in 15A NCAC 2H .0404 (g)(7), is an area
suitable for waste disposal, either in its natural state or which has been modified by planting a
vegetative cover of grasses or low growing shrubbery.
II. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the wastewater treatment and irrigation facilities by the Water Pollution
Control System Operators Certification Commission (WPCSOCC), the Permittee shall designate and
employ a certified operator to be in responsible charge (ORC) and one or more certified operator(s) to
be back-up ORC(s) of the facilities in accordance with 15A NCAC 8G .0201. The ORC shall visit
the facilities in accordance with 15A NCAC 8G .0204 or as specified in this permit and shall comply
with all other conditions specified in these rules.
3. A suitable year round vegetative cover shall be maintained
4. Irrigation shall not be performed during inclement weather or when the ground is in a condition that 1
will cause runoff. J
5. Adequate measures shall be taken to prevent wastewater runoff from the irrigation field.
2

6. The facilities shall be effectively maintained and operated as a non -discharge system to prevent the
discharge of any wastewater resulting from the operation of this facility.
1 7. The application rate shall not exceed a cumulative loading of 40.04 inches over any twelve (12)
month period at an instantaneous application rate not to exceed 0.30 inches per hour.
8. No type of wastewater other than that from Brunswick County Government Complex shall be
irrigated onto the irrigation area.
9. An automatically activated standby power source shall be on site and operational at all times. If a
generator is employed as an alternate power supply, it shall be tested weekly by interrupting the
primary power source.
10. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while
